农用地自然质量等与耕地地力评价结果一致性分析及衔接
以清丰县为例,运用GIS和多元统计分析方法,采用施肥试验中的最高单产为统一衡量标准,研究了农用地自然质量分等成果与耕地地力评价成果一致性问题并对2种评价结果进行衔接。研究结果：清丰县农用地自然质量分等成果与耕地地力评价分等结果空间一致性达到66.43%;引起农用地自然分等成果和耕地地力评价结果不一致的关键因素指标主要有耕地地力评价因素中的地下水矿化度,以及农用地自然得分评价因素中的盐渍化程度;建立了同一地区农用地自然质量指数与耕地地力评价指数之间的衔接模型。研究结论：通过衔接模型,可以实现农用地自然分等成果与耕地地力评价成果之间的相互转换。...

| Bibliography: | 36-1124/S Grading of farmland natural quality ; Cultivated land productivity assessment; Maximum yield per unit area; Qing- feng county Taking Qingfeng county as an example, based on GIS and multivariate statistical analysis method, using the maxi- mum yield per unit area in fertilization tests as the unified reference point, we studied the consistency of farmland natural quality grading result and cultivated land productivity assessment result, and explored the linking of these two kinds of results. The results indicated that the spatial consistency of farmland natural quality grading result and cultivated land productivity assessment result in Qingfeng county reached 66.43%. The key factors which caused the unconsistency of two kinds of results included the mineralized degree of groundwater （a factor in cultivated land productivity assessment） and the salinized degree of farmland （a factor in farm- land natural quality grading）. A model was established for the linking of farmland natural quality index and cul |
